UNTTEE STATES PATENT OFFICE FLORENCE MARMET, OF CINCINNATI, OHIO.

IMPROVEMENT IN ELEVATORS AND CONVEYERS FOR COKE-CRUSHERS.

Specification forming part of Letters Patent No. 187,158, dated February 6, 1877; application tiled November 17, 1875.

To all whom it may concern:

Be it known that I, FLORENCE MARMET,

of Cincinnati, Hamilton county, and State of Ohio, have invented an Improvement in Elevator and Conveyer for CokeCrusher, of which the following is a specification:

This invention relates to machines for crushing gas or other coke 5 and its object is to facilitate the delivery of the coke into the hopper of the crushing-machine.

My improvement consists in a peculiarlyconstructed hoisting and conveying apparatus, by means of which the coke is easily elevated and conveyed into the hopper.

The drawing is a perspective view ot' a machine embodying my invention.

A is the frame ofthe machine; B, the hopper, and C the shafts of the crushing-rollers D D'. The coke to ibe operated upon by the machine just described is conveyed to the hopper B by the following device: A cavity or receptacle, R,is provided below the floor S, for the hoisting and conveying box T to rest in, so that the top ot' the box may be flush with the floor, to render it convenient for the dumping therein of the large coke. Upon y the rails U of the frame work V a wheeled truck, W, is arranged to travel, its wheels w resting on the rails. This truck carries two sheave -wheels, X X', and upon the ends ot' the frame V are journaled the sheave-wheels 1 2 3 4, a sheave-wheel, 5, being also attached to the box T. Y is the hoisting, and Y' the conveying, rope, the latter arranged to pass over the windless Z, and the former having a "falP or loose end, Y", adapted to be used as a hoisting-rope, and fastened, when the box is hoisted, to any convenient projection 'top of the hopper B.

from the frame V. The rope Y starts at the point 6 on the frame V, passes over the wheels X, X', 5, and 3, in the order named, and ends in the fall Y, and it serves to elevate the box T to the proper height for conveyance to the The rope Y' starts at point 7 on the truck, passes over the, pulley 2, windlass Z, and pulleys 1 4, in the order named, and is secured to the truck at the point 8.

By this arrangement the windless is enabled, when the box is hoisted, to convey it to a position over the hopper for delivery, the peculiar arrangement of the hoisting-rope enabling this operation to proceed.

By reversing the motion of the windlass, the box, after being emptied, can be returned to a position over the hole R, for lowering by rope Y and relling. The box T is provided with hooks tt, faced in opposite directions, and a swinging door, t2, having a swinging arm, t3, operated by rope t4. This device enables the operator, when the box is elevated and over the hopper, to dump the contents into the hopper, the rope acting to release the arm t3 on both sides, and allow the coke to open the door t2.

I claim- The combination of track U, truck W, ropes Y Y', box T, and windlass Z, the ropes being connected, and passing the necessary pulleys, substantially in the manner and for the purpose specied.

In testimony of which invention I hereunto set my hand.
